Here's view of the tram line you don't see any more - green hills to the right, and beach to the left! Can anyone identify any of the (few) landmarks shown to give an exact position?
Also, do you know when the tram line was extended past Causeway Bay, to narrow down the date? The HK Tramways website just says:
1903: The construction of a single-track system began and it ran from Kennedy Town to Causeway Bay. The route was later extended to Shau Kei Wan.
I'm not sure if that "later" means before or after the trams started running the following year.
